STUlVIP-PULLING APPARATUS.

Patented Apr. 14, 1914..

Application filed November 4, 1912 Serial No. 729,392.

To all whom it may concern:

Be it known that we, JAMES A. GORMAN and HENRY ll/ SUMNER, citizens of the United States, residing at Seattle, in the county of King and State of Washington,

have invented certain new and useful Improvements in Stump-Pulling Apparatus, of which the following is a specification.

Our invention relates to apparatus of the above type embodying a hauling drum with which a driving member is releasably engaged whereby the latter can be disconnected quickly from time to time, and it has for a primary object to provide a generally simplified and improved structure which is durable and capable of operation in an eflicient manner.

A further object resides in the provision of an improved drum structure by which cable as hauled in will be wound more perfectly.

Other objects will be set forth as our description progresses and those features of construction, arrangements and combinations of parts on which we desire protection, succinctly defined in our annexed claims.

Referring to the accompanying drawings wherein like numerals of reference indicate like parts throughout: Figure 1 is a perspective of a stump pulling apparatus constructed in accordance with our invention. Fig. 2 is a vertical longitudinal section thereof with the sweep head elevated. Fig. 8 is a fragmentary horizontal section on line 3-3 of Fig. 4:. Fig. 4 is a fragmentary transverse section, parts being broken away. Fig. 5 is a fragmentary section through one edge portion of the drum, illustrating more particularly the provision for making the cable fast on the drum. Fig. 6 is a section on line 6-6 of Fig. 5, and Fig. 7 is a fragmentary perspective of the drum shaft and locking key and guard in disengaged relation.

Referring to the drawings by numerals of reference, 1 indicates a base conveniently comprising converging skid members 1 con nected by cross bar or bed member 2 having concave edge flanges 3 which seat on skid members 1 and are secured thereto, as by bolts 4. Connecting bar or bed member 2 is provided with a vertically disposed stub shaft 5 having a base flange or boss 6 and formed in its upper end portion with a pcripheral groove 7 with which cutouts 7 extending inwardly from the upper end of the shaft, communicate. Cutouts 7 are suitably spaced to provide diametrically opposite lugs 8 for interlocking engagement with similar lugs 10 of a key 11. Key 11 is in the form of an annulus having an inwardly proectmg annular flange 11' from which latter lugs 10 project, see Fig. 7.

Reference numeral 12 indicates a winding drum journaled on shaft 5 and seated on the base flange or boss 6 thereof, the said drum having side flanges 12, 12', the latter of which is provided on its inner face with a rib or annular extension 12 which projects inwardly from the adjacent end of the drum hub to engage and direct the hauling cable, as 13 (see Fig. 4.) away from the adjacent end of the hub'thus preventing crowding of the cable at the lower end of the hub and thereby insuring of the cable being wound in layers in a more perfect manner. The under face of drum flange 12 is provided :with ratchet teeth 14 with which a gravity pawl 15 engages. Pawl 15 is fulcrumed at 15 to an anchor cable engaging hook 16 of the base and provided on its outer weighted end portion with an actuator consisting of a cam 17 pivoted to said pawl and adapted to have bearing on the adjacent flange 3 of bar or bed member 2. By grasping the handle 17 of cam 17 and swinging the same outwardly, pawl 15 is withdrawn from ratchet teeth 14, thereby releasing drum 12 for running out of cable 13.

Reference numeral 18 indicates a sweep head formed with an opening 19 for reception of the sweep 20, which latter is adapted to have its outer end supported by a suitable bearing member which, as now considered, comprises a runner 21, having its forward end portion turned up, as at 21, to guide the outer end portion of the sweep over obstructions,

Reference numeral 22 indicates a hook arranged rearwardly of upturned end portion 21, adapted to be connected with a suitable draft connection, not shown.

Reference numeral 23 indicates a pin or stud, fixed to head 18 and being slidably received in an aperture, formed in the upper .end portion of shaft 5, for guiding the head vertically with respect to drum 1" This relative movement of the sweep head effects the alternative engagement and disengagement of interlocking members 2 1, provided on said head and drum respectively. These locking parts 24; are preferably in the form of ratchet teeth whose abutting forward faces are slightly under-cut, as shown, to prevent accidental lifting of the sweep head during the hauling in of the cable. For lifting head 18 vertically, we ournal therein a rock shaft 25 which shaft is provided with eccentrics 26 which have bearing on the upper edge of key 11. A handle 25 is fixed to a projecting end of shaft 25 for rocking the latter.

7 Reference numeral 27 indicates stops for limiting movement of handle 2?.

To lock drum 12 011 shaft 5, key 11 is slipped over the upper end portion of said shaft, with its lugs 10 engaging in the cutcuts 7 until groove 7 is entered. Key 11 is then given a quarter turn, following which a guard member 11 is positioned in one of the cut-outs 7 and between the lugs 10 of the key. 7

Reference numeral 28 indicates a cable securing block, coacting with which is an eccentric clamping member 29. Block 28 is fixed to a plate 30 of bar or bed 2, as by a bolt 31.

Reference numeral 32 indicates a headed guide lug fixed to plate 30 opposite clamping member 29 for guiding and holding the cable in proper relation to block 28. Hauling cable 13 has its inner end enlarged, as at 13, and engaged in a tapered socket 13 of drum flange 12, which socket has a restricted entrance opening extending inwardly from the edge of the drum flange of a width approximately corresponding to the diameter of the cable. This permits of the cabl being first inserted, as indicated by dotted lines in Fig. 5, and then drawn downwardly to bring its enlarged end to a firm seating in the socket. We close the entrance opening of socket 13 by a keeper 35 which is normally held by the cable against accidental displacement. This keeper comprises a curved plate which is inserted into cutcuts or seats 35, formed in the inner face of said socket on opposite sides of the entrance opening thereof and inwardly of the upper end of the socket, prior to the drawing down of the enlarged cable end 13 into the socket.

In operation a suitable anchoring cable or other medium, (not shown) is engaged with hook 16. The hauling cable is passed from drum 12 to the stump and then back to the apparatus wherein it is passed around block 28 in the groove thereof, and between lug 32 and clamp 29, as more clearly shown in Fig. 3.

Having thus described our invention what we claim as new, and desire to secure by Letters Patent of the United States of America, is
